In a ‘dynamo’,
|
|
Mechanical energy is converted to heat energy
|
|
|
Electrical energy is converted to mechanical energy
|
|
|
Mechanical energy is converted to electrical energy
|
|
|
Electrical energy is converted to magnetic energy
|
Explanation:
Detailed explanation-1: -So, a dynamo converts mechanical energy into electrical energy. It used rotating coils of wire and magnetic fields to convert mechanical rotations into a pulsing direct electric current.
Detailed explanation-2: -An electric generator is a device used to convert mechanical energy into electrical energy. The generator is based on the principle of “electromagnetic induction” discovered in 1831 by Michael Faraday, a British scientist.
Detailed explanation-3: -The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy. Different types of turbines include steam turbines, combustion (gas) turbines, hydroelectric turbines, and wind turbines.
